Proper comparison of Hansen's and Delaunay's equations of Longitude, Latitude and Parallax [of the moon] much needed. Description of such comparisons as already exist. JCA's own parallax tables. Tables of Moon's Ephemeris might be obtained from Hind: JCA will enquire. Hill's computation of the perturbations of Jupiter and Saturn very worthy.

Copy of letter to W. De La Rue
Part of Papers of John Couch Adams
[JCA's comments on De La Rue's speech on awarding Gold Medal of RAS] Acknowledges copy of Hansen's letter sent. Disagrees with H's assertion that he never contested JCA's theory of the secular acceleration of the moon: H caused LeVerrier to attack JCA and Delaunay, and is now adapting his own theory without admitting it might be wrong.

Letter of introduction for Pierce. Plana convinced of JCA's and CD's expression of the secular acceleration of moon's mean motion. Hansen and LeVerrier might yet be convinced.
